I follow a wide range. I tend to lean towards #blog, #photography, #travel, and some others where I can get to know who the people are as opposed to simply voting on a given type of content. I used to focus a lot on the #steemit and #introduceyourself tags to help new members get acquainted with Steemit. I put a bunch of "howto" and general useful Steemit navigation tips out there in my early days, but many of the tools I previously used are no longer active. Also, Steemsql went from.being free to a paid service, so I couldn't justify continuing to use it to help the community fight spammers if I was constantly losing money on the effort.
